Is there any difference in ultrasonic cleaners?
Granbo: Ultrasonic cleaners come in 3 categories,
Mini type for cleaning contact lenses, etc. These are very light duty cleaners with small
transducers and very simple generators that are not very efficient.They should never be usedfor critical cleaning jobs.
The second type are the dental cleaners and small lab size tabletop cleaners, these have aheaver transducer and a better generator and are efficient in cleaning small parts and labglass.
The third type is the industrial heavy-duty type with very heavy compound transducersand rugged generators that produce high wattage per transducer. These clean more efficientlyand can be used for production cleaning. Tanks are heavy-duty welded 304 or 316L stainlesssteel with overflows and drain ports. Our KR series are this type.
How to choose ultrasonic frequency?
Granbo: Ultrasonic requency is suggested based on cleaning objects'material and pollutants in theobjects. Most ultrasonic cleaners operate between 20K to 120 KHz. The system frequency touse depends on the type of cleaning required.
The lower frequencies produce larger cavitation bubbles with more abrasive cleaning.Thesefrequencies are recommended for coarse cleaning needs such as removal of lapping
compounds from durable metal surfaces. For fine cleaning of very delicate items such asjewelry and soft metals with polished surfaces, higher frequency may be more suitable.
How to choose a good ultrasonic cleaner?
Granbo: Choose the suitable ultrasonic frequency according to the above suggestions.Inner size of cleaning tank: It should be bigger than cleaning objects' size.
Core element: The core element of an ultrasonic cleaner is ultrasonic transducer. The qualityof ultrasonic transducer influences the service life of an ultrasonic cleaner greatly.
Ultrasonic power: The larger the volume of solution, the more ultrasonic power will be neededfor cleaning. Most cleaners run at an average power of 50 to 100 watts per gallon, so thelarger the tank the more power you need. Simply to say, we can think more power usuallyindicates faster and more effective cleaning.
